Hi all,

Very Simple question which I cant figure out / find the answer too.

Just downloaded and installed UAG RC0 on a Windows 2008 R2 Virtual Server.

1 NIC Configured as External inside a DMZ
1 NIC Configured as Internal inside the Domain with no default Gateway.

I changed very little from the default install.

I am trying to install the default UAG portal so I can test how applications would look and feel on it.

So I set up a Http Trunk "Portal.mydomain.com" with an address of my internal network card and all the defaults.

This is where I seem to be missing something basic...

How can I now Browse to this page from inside my network or even from the server itself?! Why cant I browse to Portal.mydomain.com or even my using the IP address?

I've full admin rights.

Thanks :)

Hi Jason. The trunk must be assigned to an external IP. I am not saying this is the solution, but try first this.

Hi Amigo. The access from the internal network is likely being blocked by ISA Server due to the spoofing architecture. If ISA receives a request in the external interface coming from a source address of the internal network the packet will get blocked due to anti-spoofing prevention. You should put in place in your router/firewall a NAT translation when going from the internal network to the DMZ IP address of your IAG.

Hope it helps

Hi Raul,

We have assigned the Truck an address from our DMZ.

However we still cant access the webpage so I cant tell if its working at all.

Surely I should be able to Browse \ View the site from the server itself or from my internal network?

I have to be missing something here, how can anyone build or customise a site without being able to view it?
